operator [] method

  1. @override
bool operator [](
  1. int index
)
override

The object at the given index in the list.

The index must be a valid index of this list, which means that index must be non-negative and less than length.

Implementation

@override
bool operator [](int index) {
  RangeError.checkValidIndex(index, this, 'index', _length);
  return (_data[index >> _entryShift] &
          (1 << (index & _entrySignBitIndex))) !=
      0;
}
